Abstract

PARA LA FUNDICION DE PERDIGON, PELLETS DE HIERRO ESPONJOSO EN FORMA REDUCIDA, HIERRO BRUTO SOLIDO, O SIMILARES, SE PROPONE, INTRODUCIR EL CALOR LATENTE DE FUSION A MEDIO MECHERO DESDE ABAJO, Y SE AJUSTA EL CONTENIDO DE CARBONO CORRESPONDIENTE BAJO LA DEFORMACION DE ADITIVOS DE CARBONO PARA LA CARGA POR LA COMBUSTION DE HIDRATOS DE CARBONO, POR BAJA ESTEQUIOMETRIA EN EL BAÑO DE FUNDICION. POR DISMINUCION DEL FLUJO DE OXIGENO, PRINCIPALMENTE LA DISMINUCION DE LA CANTIDAD DE OXIGENO DE LA ESTEQUIOMETRIA CON UN ARQUEO DE 0.9 APROXIMADAMENTE, ASI COMO EN SU CASO ADICION DE FORMADORES DE ESCORIA, SE DISMINUYE AL MISMO TIEMPO LA AGRESIVIDAD DE LA ESCORIA.
